Zoas receding

[dead rock]

I have these grim reapers. They were completely covered and now they look as though something has been eating on them or they have been receiving. Does anybody know what’s going on with them?

Do you have a nem because mine once walk all over my Duncan once and did not make it

 

[dead rock]

No nems

 

[Tang fastic]

No nems

Ok now it is confusing

But do have any other corals near by because they potentially could have stung it

Otherwise do have an Aiptasia problem that could be it

Or maybe you have just forgotten to do a water change it is all ways a option

Maybe what happened to me is happening to you…

Exosphere’s vanishing - losing colony need help

No idea here everyone Bought a colony of 25 heads of exosphere. Looked very healthy. Within a few days I was down to 15. Looked like all the lower and smaller ones melted and turned to mush. I dipped it in revive and coral rx and gave a light scrubbing with a soft brush and got all the mush...

These all came from two polyps I bought last September I’ve had like I’m sure everyone else colonies that just starts doing bad. I believe I can dip it and have a high success rate on saving it wanted to post a picture in case there’s something that I’m missing I recently had a ATI water sample ran and I was very low on iodine high levels of lithium and a few other things were a little off. My salinity was down. I am raising it up. I had 3 meters that showed perfect salt level, but I had tested at my local Fish store and ATI says I’m low so I bought a new salinity Hannah checker and it shows that my salt is low. I have currently brought that salinity up.

Have you had algae or anything like that bothering them? Any noticeable changes in your tank regarding lighting or flow? Any swings in your parameters?

All of my zoas had started closing and I thought it was the unknown melting issue people have. But after recalibration of my hanna checker with proper solution, I realized it had been reading high .003.. after slowly bringing it back up to 1.026 all of my zoas have bounced back and started opening again. Granted, their stalks are a little thin bc of the few weeks they were closed, but at least they are on the rebound.

So now I'm always suggesting people recheck their refractometer and or hanna checker when they are seeing closed zoas. I think a lot of people use RO to calibrate but it's not recommended.

I had two refractometer and an Apex system all showing perfect salinity, but my salinity’ was low. It’s been like this for a very long time the Zoas grew on that towel like that and have not really been moved. They were looking great. The light has not really changed. I have some zoa right beside it that are doing great.

Also, one contributing factor I was dealing with high phosphate and nitrate for a little while because I stacked some mushrooms on top of each other that killed some of them so parameter was a little loud but that’s been a while back

 

[Tang fastic]

That would be it

 

[dead rock]

I would guess that it could be in but that’s been three or four weeks ago and has been corrected

Oh I stand corrected

 

[dead rock]

I certainly appreciate all the help as it seems this happens now and again, and it’s my goal to keep my parameters in check so that some of my nice coral can multiply

ive lost a ton of zoas due to the little asterina looking starfish eating zoas. not all of them... only the green colored ones. I've had to manually remove them whenever i see them. i have a video of me pulling out a frag plug and a starfish is on top of a zoa head eating it. i plucked it off... i lost hundreds of fire and ice, eagle eyes, radioactive dragon eye zoas.. very sad haha

I have also had that problem. With Asterina starfish and Emerald crabs I probably have 12 Emerald crabs in my sump those things will eat anything from Zoas lps to Montipora I extract every starfish I see I look out for them every morning. I believe I will pay more attention to those Zoas particularly you may be on to something it’s funny how sometimes you look over the simple stuff in search of a more difficult answer I hope I find starfish
